Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuse strips require complex arrangements and conductor tracks leading to end-face terminal clamps, making them bulky and difficult to connect outgoing lines directly.
Innovation Solution
A fuse strip design with lateral outgoing contacts equipped with clamping springs for screwless connection, eliminating the need for end-face terminal clamps and conductor tracks, allowing direct and accessible connection of outgoing lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If end-face terminal clamps with conductor tracks are used, then outgoing lines can be connected, but the fuse strip becomes bulky and complex in arrangement
Solution Approach 1:
The patent relocates the outgoing contacts from the end-face region to the lateral side of the fuse strip. This dimensional change eliminates the need for conductor tracks extending through the housing and allows outgoing lines to be connected directly at the side, significantly simplifying the internal arrangement and reducing structural complexity while maintaining ease of connection.
Solution Approach 2:
The invention extracts and removes the end-face terminal clamps and their associated conductor tracks from the fuse strip structure. By eliminating these components entirely and replacing them with lateral outgoing contacts, the patent reduces the overall complexity of the arrangement while preserving the essential function of connecting outgoing lines.
2Ease of operation
If end-face terminal clamps are used, then outgoing lines can be connected, but the fuse strip shape becomes longer and more complex
Solution Approach 1:
By moving the connection points from the end-face to the lateral side of the fuse strip, the patent enables outgoing lines to be accessed from the side rather than requiring the strip to extend significantly in length. This dimensional repositioning reduces the effective length requirement while maintaining easy accessibility for connection operations.
3Productivity
If screwless clamping springs are used, then assembly is simplified, but additional openings are needed for tool access
Solution Approach 1:
The clamping springs are designed to automatically engage and secure outgoing lines upon insertion, eliminating the need for manual screw fastening. This self-service mechanism significantly accelerates the assembly process. The additional openings provided in the lateral wall allow tool access for releasing the clamping action when disassembly is required, balancing automation with controllability.

AI summary
The invention relates to a fuse strip, comprising a housing, preferably made of plastics material, with at least two means, arranged in the housing, for receiving fuse elements, with clamping feet provided on the underside of the housing, wherein a contact for contacting the associated conductor rail is configured in the region of each clamping foot. Laterally of the housing, in the region of each clamping foot, there is provided a laterally integrally formed terminal block which receives a respective outgoing contact for connecting an outgoing line. In a preferred embodiment, each terminal block contains a guide for receiving a contact pin of an adapter strip in such a way that when the adapter strip is attached, each contact spring is electrically connected to the associated outgoing contact of each terminal block and wherein the adapter strip is provided with an end-face module comprising terminal clamps.
